The manual also states that you should calculate a derating factor of 1.25 for NOC (normal operating conditions) which would bring a 425 watt array right to the recommended 340 watts.
Also remember that while Blue Sky doesn't like over capacity at the input of the controllers, they WILL accept it and simply clip the output amperage to the batteries at 25 amps. A typical solar array will only be producing maximum output for a short period as the sun's azimuth changes with regard to the panels' surface........... unless you employ an automatic solar tracking device that always points your array towards the sun at the optimum angle for maximum solar radiance.
